History of the term “Blockchain.”

In his 1982 dissertation “Computer Systems Established, Maintained, and Trusted by Mutually Suspicious Groups,” cryptographer David Chaum presented a blockchain-like protocol for the first time. 

Stuart Haber and W. Scott Stornetta described their work on a cryptographically secure chain of blocks in 1991. They sought to create a system that prevented tampering with document timestamps. The term “Block” gets introduced.

In 2008, Satoshi Nakamoto created bitcoin, the first practical application of blockchain technology. That technology, however, is based on concepts from the 1990s. In the bitcoin white paper’s footnotes, Nakamoto also mentions it.
